| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. The Company’s foreign subsidiaries functional currency is the U.S. dollar. Transaction gains and losses are recognized in earnings. The Company is subject to foreign exchange rate fluctuations in connection with the Company’s international operations. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Reclassification of Prior Year Presentation Certain prior year amounts related to revenue and cost of sales for our POS and TOS business operations have been reclassified for consistency with the current year presentation, reflecting one reportable segment. These reclassifications had no effect on the reported results of operations. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with a maturity of three months or less at the time of purchase, to be cash equivalents. At various times, the Company has amounts on deposit at financial institutions in excess of federally insured limits. Fair Value The carrying value of cash and cash equivalents, accounts receivable, prepaid expenses, deposits and other receivables, accounts payable, and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The fair value hierarchy promulgated by GAAP consists of three levels: • Level one — Quoted market prices in active markets for identical assets or liabilities; • Level two — Inputs other than level one inputs that are either directly or indirectly observable; and • Level three — Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use. Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. The Company has no assets that are measured at fair value on a recurring basis and there were no assets or liabilities measured at fair value on a non-recurring basis during the year ended April 30, 2018 . Accounts Receivable Accounts receivable represent amounts due under agreements with pharmaceutical and biotechnology companies for TOS and amounts due under agreements with patients for POS. At each reporting period, the Company evaluates open accounts receivable for collectability and records an allowance for potentially uncollectible accounts. For April 30, 2018 and 2017 , the allowance for these accounts was $13,000 and $56,000 , respectively. Accounts receivable is also comprised of certain unbilled accounts receivable for services completed under TOS that have not been billed as of the balance sheet date. As of April 30, 2018 and 2017 , the Company had unbilled receivables of $2.1 million and $1.6 million , respectively. Restricted Cash As of April 30, 2018 and 2017 , the Company has restricted cash of $150,000 and $150,000 , respectively, which is classified as a non-current asset on the consolidated balance sheets. This restricted cash serves primarily as collateral for corporate credit cards to provide financial assurance that the Company will fulfill its obligations. The cash is held in custody by the issuing bank, is restricted as to withdrawal or use, and is currently invested in an interest-bearing Certificate of Deposit (“CD”). As of November 2017, the Company has switched vendors and is no longer obligated to restrict this cash. The CD matures in the second quarter of fiscal 2019 at which time the Company will not renew and will no longer account for this as restricted cash. Property and Equipment Property and equipment is recorded at cost and primarily consists of laboratory equipment, furniture and fixtures, and computer hardware and software. Assets in progress include equipment not yet placed in service for the new laboratory facility. Depreciation and amortization is calculated on a straight-line basis over the estimated useful lives of the various assets ranging from three to seven years. Property and equipment consisted of the following (in thousands): April 30, 2018 2017 Furniture and fixtures $ 73 $ 74 Computer equipment and software 973 872 Laboratory equipment 2,490 918 Assets in progress 15 472 Leasehold improvements — 2 Total property and equipment 3,551 2,338 Less: Accumulated depreciation and amortization (1,468 ) (1,122 ) Property and equipment, net $ 2,083 $ 1,216 Depreciation and amortization expense was $360,000 and $168,000 for the years ended April 30, 2018 and 2017 , respectively. The company disposed of fixed assets which reduced total property and equipment and accumulated depreciation by $16,000 and $(13,000) , respectively, leaving a gain on disposal of fixed asset of $3,000 . Additionally, included in “Laboratory equipment” as of April 30, 2018 and 2017 is a capital lease asset of $130,000 and $124,000 , respectively. Depreciation and amortization expense relating the capital lease was $26,753 and $24,045 for the years ended April 30, 2018 and 2017 , respectively. Capital Lease In November 2014, the Company entered into a lease for laboratory equipment. The lease was determined to be a capital lease that has costs of approximately $149,000 , at inception, through November 2019. The current monthly capital lease payment is approximately $3,000 . The following is a schedule by years of future minimum lease payments under this capital lease together with the present value of the net minimum lease payments as of April 30, 2018 (table in thousands): For the Years Ended April 30, 2019 $ 28 2020 16 Total minimum lease payments 44 Less: amount representing interest (2 ) Present value of minimum payments 42 Less: current portion (26 ) $ 16 The present value of minimum future obligations shown above is calculated based on interest rate of 5% . The short-term and long-term components of the capital lease obligation are included in accrued liabilities and other non-current liabilities, respectively at April 30, 2018 and 2017 . Impairment of Long-Lived Assets Impairment losses are to be recognized when the carrying amount of a long-lived asset is not recoverable or exceeds its fair value. The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that a carrying value may not be recoverable. The Company uses estimates of future cash flows over the remaining useful life of a long- lived asset or asset group to determine the recoverability of the asset. These estimates only include the net cash flows directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of the asset or asset group. The Company has not recognized any impairment losses for the Company’s long-lived assets for the years ending April 30, 2018 and 2017 . Other long term assets Other long term assets represents amount relating to lease deposits for our Hackensack, New Jersey and Rockville, Maryland locations. Goodwill Goodwill represents the excess of the cost over the fair market value of the net assets acquired including identifiable assets. Goodwill is tested annually, or more frequently if circumstances indicate potential impairment, by comparing its fair value to its carrying amount. The determination of whether or not goodwill is impaired involves significant judgment. Although the Company believes its goodwill is not impaired, changes in strategy or market conditions could significantly impact the judgments and may require future adjustments to the carrying value of goodwill. The Company uses a two-step process to test for goodwill impairment. The first step is to screen for potential impairment, while the second step measures the amount of the impairment, if any. The first step of the goodwill impairment test compares the fair value of each reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired. If the carrying value of the reporting unit’s net assets, including goodwill, exceeds the fair value of the reporting unit, then the Company determines the implied fair value of goodwill. If the carrying value of goodwill exceeds its implied fair value, then an impairment of goodwill has occurred and an impairment loss would be recognized for the difference between the carrying amount and the implied fair value of goodwill as a component of operating income. The implied fair value of goodwill is calculated by subtracting the fair value of tangible and intangible assets associated with the reporting unit from the fair value of the unit. The Company tests for goodwill impairment at the reporting unit segment level. The Company has not recognized any impairment losses for the Company’s goodwill for the years ended April 30, 2018 and 2017 . Deferred Revenue Deferred revenue represents payments received in advance for products to be delivered. When products are delivered, deferred revenue is then recognized as earned. Other Non-Current Liabilities Other non-current liabilities represents amounts relating to deferred rent for our Rockville, Maryland laboratory facility, non-current portion of capital lease for laboratory equipment and uncertain tax positions relating to one of our foreign entities. Revenue Recognition The Company derives revenue from its TOS and POS businesses. Translational oncology solutions offer a preclinical TumorGraft platform to pharmaceutical and biotechnology companies using proprietary TumorGraft studies, which the Company believes may be predictive of how drugs may perform in clinical settings. Personalized oncology solutions assist physicians by providing information to help guide the development of personalized treatment plans for their patients using our core offerings, including testing oncology drugs and drug combinations on personalized TumorGrafts, and through other products. The Company recognizes revenue when the following four basic criteria are met: (i) a contract has been entered into with its customers; (ii) delivery has occurred or services rendered to its customers; (iii) the fee is fixed and determinable as noted in the contract; and (iv) collectability is reasonably assured. The Company utilizes a proportional performance revenue recognition model for its TOS business, under which it recognizes revenue as performance occurs, based on the relative outputs of the performance that have occurred up to that point in time under the respective agreement, typically the delivery of reports to its customers documenting the results of testing protocols. When a TOS or POS arrangement involves multiple elements, the items included in the arrangement (deliverables) are evaluated to determine whether they represent separate units of accounting. The Company performs this evaluation at the inception of an arrangement and as each item in the arrangement is delivered. Generally, the Company accounts for a deliverable (or a group of deliverables) separately if: (i) the delivered item(s) has standalone value to the customer, and (ii) if the Company has given the customer a general right of return relative to the delivered item(s) and the delivery or performance of the undelivered item(s) or service(s) is probable and substantially in the Company’s control. All revenue from contracts determined not to have separate units of accounting is recognized based on consideration of the most substantive delivery factor of all the elements in the contract or if there is no predominant deliverable upon delivery of the final element of the arrangement. Cost of Oncology Solutions Cost of oncology solutions relates to our TOS and POS business units. TOS costs consist of direct costs related to mice purchases and maintenance costs for studies completed internally and charges from CROs for studies handled externally. Indirect costs include salaries for personnel directly engaged in providing TOS products. All costs of performing studies in-house are expensed as incurred. All TOS costs of performing studies from external sources, if any, are expensed when incurred. POS consists of costs related to implantations, drug panels, tumor boards, and gene sequencing services, as well as indirect internal costs, such as salaries for personnel directly engaged in these products. Direct costs associated with implantation revenues are primarily related to mice purchases and maintenance and shipping of tumor tissue. Direct drug panel costs are primarily incurred from mice purchases and maintenance and drug purchases. Direct tumor board costs are primarily related to physicians’ honorariums and any tumor board participation costs such as travel, lodging and meals. Direct gene sequencing costs are primarily related to costs billed from the gene sequencing service provider. All POS costs are expensed as incurred. Research and Development Research and development costs represent both costs incurred internally for research and development activities, including personnel costs and mice purchases and maintenance, as well as costs incurred externally to facilitate research activities, such as tumor tissue procurement and characterization expenses. All research and development costs are expensed as incurred. Sales and Marketing Selling and marketing expenses represent costs incurred to promote the Company’s products offered, including salaries, benefits and related costs of our sales and marketing personnel, and represent costs of advertising and other selling and marketing expenses. All sales and marketing costs, including advertising costs, are expensed as incurred. Basic and Dilutive Loss Per Common Share Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s common stock purchase warrants and stock options. For the twelve months ended April 30, 2018 and 2017 , basic and dilutive loss per share were the same, as the potentially dilutive securities did not have a dilutive effect. Year Ended April 30, 2018 2017 Basic and diluted net loss per share computation (dollars in thousands except per share amounts) Net loss attributable to common stockholders $ (1,476 ) $ (6,884 ) Weighted Average common shares 10,991,105 10,684,395 Basic and diluted net loss per share $ (0.13 ) $ (0.64 ) The following table reflects the total potential stock-based instruments outstanding at April 30, 2018 and 2017 that could have an effect on the future computation of dilution per common share: Year Ended April 30 2018 2017 Stock options 2,705,845 2,308,704 Warrants 2,004,284 2,004,284 Total common stock equivalents 4,710,129 4,312,988 Stock-based Payments The Company typically recognizes expense for stock-based payments based on the fair value of awards on the date of grant. The Company uses the Black-Scholes option pricing model to estimate fair value. The Black-Scholes option valuation model was developed for use in estimating the fair value of short-traded options that have no vesting restrictions and are fully transferable. The option pricing model requires the Company to estimate certain key assumptions such as expected life, volatility, risk free interest rates and dividend yield to determine the fair value of stock-based awards. These assumptions are based on historical information and management judgment. The risk-free interest rate used is based on the United States treasury security rate with a term consistent with the expected term of the award at the time of the grant. Since the Company has limited option exercise history, it has generally elected to estimate the expected life of an award based upon the Securities and Exchange Commission-approved “simplified method” noted under the provisions of Staff Accounting Bulletin No. 107 with the continued use of this method extended under the provisions of Staff Accounting Bulletin No. 110. Estimated volatility is based upon the historical volatility of the Company's common stock. The Company does not anticipate paying a dividend, and therefore, no expected dividend yield was used. The Company expenses stock-based payments over the period that the awards are expected to vest, net of estimated forfeitures. If actual forfeitures differ from management’s estimates, compensation expense is adjusted. The Company expenses modification charges in the period of modification and, if required, over the remaining period the awards are expected to vest. The Company will report cash flows resulting from tax deductions in excess of the compensation cost recognized from those options (excess tax benefits) as financing cash flows, if they should arise. Income Taxes Deferred income taxes have been provided to show the effect of temporary differences between the recognition of expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. In assessing the realizability of deferred tax assets, the Company assesses the likelihood that deferred tax assets will be recovered through tax planning strategies or from future taxable income, and to the extent that recovery is not likely or there is insufficient operating history, a valuation allowance is established. The Company adjusts the valuation allowance in the period management determines it is more likely than not that net deferred tax assets will or will not be realized. Changes in valuation allowances from period to period are included in the tax provision in the period of change. As of April 30, 2018 and 2017 , the Company provided a valuation allowance for all net deferred tax assets, as recovery is not more likely than not based on an insufficient history of earnings. Tax positions are positions taken in a previously filed tax return or positions expected to be taken in a future tax return that are reflected in measuring current or deferred income tax assets and liabilities reported in the consolidated financial statements. Tax positions include, but are not limited to, the following: • An allocation or shift of income between taxing jurisdictions; • The characterization of income or a decision to exclude reportable taxable income in a tax return; or • A decision to classify a transaction, entity or other position in a tax return as tax exempt. The Company reflects tax benefits only if it is more likely than not that we will be able to sustain the tax position, based on its technical merits. If a tax benefit meets this criterion, it is measured and recognized based on the largest amount of benefit that is cumulatively greater than 50% likely to be realized. The Company has recorded $151,000 and $121,000 of liabilities related to uncertain tax positions relative to one of its foreign operations as of April 30, 2018 and 2017 , respectively. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties on the Company’s balance sheets at April 30, 2018 and 2017 , and has not recognized interest and/or penalties in the statement of operations for either period. We do not anticipate any significant unrecognized tax benefits will be recorded during the next 12 months. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. In addition, this guidance requires new or expanded disclosures related to the judgments made by companies when following this framework and additional quantitative disclosures regarding contract balances and remaining performance obligations. On July 9, 2015, the FASB voted to defer the effective date by one year to December 15, 2017 for interim and annual reporting periods beginning after that date. Early adoption of ASU 2014-09 is permitted but not before the original effective date (annual periods beginning after December 15, 2016). When effective, ASU 2014-09 prescribes either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients; or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company will adopt this guidance on May 1, 2018. The Company has evaluated the overall impact that ASU 2014-09 will have on the Company’s consolidated financial statements, as well as the expected timing and method of adoption. The Company established an implementation team, including external advisers, and is finalizing the review of the Company’s revenue portfolio and related contracts across its various business units and geographies. Discussions regarding changes to the Company’s current accounting policies and practices remain ongoing and preliminary conclusions are subject to change. Upon adoption, the Company will recognize revenue from contracts with customers as each performance obligation is satisfied, either at a point in time or over a period of time, based on when control transfers to customers. The adoption of this update is not expected to have a material impact on our consolidated financial statements. The Company plans to adopt the new revenue recognition standard under the modified retrospective transition method by recognizing the cumulative effect of applying the standard as an adjustment to the Company’s Balance Sheet. The Company has been assessing the impact of the new revenue recognition standard, and the Company does not anticipate being able to provide the full impact on the Balance Sheets or Statements of Operations until they complete the review of all of their contracts during fiscal 2019. From the initial review and assessment of a sample of contracts with customers, the Company will evaluate the measurement and timing of revenue recognition for certain of its co-clinical contracts under the new standard. The Company will also provide enhanced disclosure regarding revenue recognition, including disclosures of revenue streams, performance obligations, variable consideration and the related judgments and estimates necessary to apply the new standard. The Company plans to adopt the new revenue recognition standard under the modified retrospective transition method by recognizing the cumulative effect of applying the standard as an adjustment to the Company’s Balance Sheet. Until the Company completes testing of the new revenue recognition standard, the Company does not anticipate being able to provide the impact of the new standard on the Balance Sheet or Statements of Operations; however, from the initial review and assessment of a sample of contracts with customers, the Company does not anticipate the new accounting pronouncement to have a material impact on the Company’s financial statements, except enhanced disclosure regarding revenue recognition, including disclosures of revenue streams, performance obligations, variable consideration and the related judgments and estimates necessary to apply the new standard. In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. The amendments in this update state that in connection with preparing financial statements for each annual and interim reporting period, an entity’s management should evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued, when applicable). The amendments in this update are effective for the annual reporting period beginning after December 15, 2016 and for annual periods and interim periods thereafter. Early application is permitted. The Company adopted this updated in fiscal 2018 and did not have a material impact on our consolidated financial statements. In February 2016, the FASB ASU No. 2016-02, Leases. The new standard will require most leases to be recognized on the balance sheet which will increase reported assets and liabilities. Lessor accounting remains substantially similar to current guidance. The new standard is effective for annual and interim periods in fiscal years beginning after December 15, 2018, which for us is the first quarter of fiscal 2019 and mandates a modified retrospective transition method. We are currently assessing the impact of this update on our consolidated financial statements. In April 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting”. The new standard simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU No. 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this standard in fiscal 2018 and, as expected, it did not have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” . The new standard attempts to reduce diversity in practice in how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 provides guidance on eight specific cash flow issues. The new guidance will be effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted including adoption in an interim period. We do not intend to early adopt and the adoption of this update is not expected to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): “Simplifying the Test for Goodwill Impairment”. The update simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. It affects public entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. A public entity that is a U.S. Securities and Exchange Commission ("SEC") filer should adopt the amendments in this update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. For the Company, the amendments are effective January 1, 2020. The Company has early adopted this ASU in fiscal 2018. The adoption of this ASU did not have a material impact on our consolidated financial statements. |
